Question

State whether true or false :
An electromagnet can produce very strong magnetic force as compared to permanent magnet.

• A. True
• B. False

Answer 1

The correct option is A True

A simple electromagnet consisting of a coil of wire wrapped around an iron core. A core of ferromagnetic material like iron serves to increase the magnetic field created. The strength of magnetic field generated is proportional to the amount of current through the winding.An electromagnet can produce very strong magnetic force as compared to permanent magnet.
